“The Android 2.2 OS upgrade must be downloaded over Wi-Fi and consists of three individual packages. Each package will first download and then install. Installation and download times will vary depending on your Wi-Fi connection and data speeds. The average time for download and installation of the first and second packages is 5 – 10 minutes each, and 20 – 30 minutes for the third package. There will be a power cycle after each of these packages has installed. You may be required to re-establish a Wi-Fi connection after the power cycle.”
